A Comparison Between Low-Volume Referring Regional Centers and a High-Volume Referral Center in Quality of Preoperative Metastasis Detection in Esophageal Carcinoma

Abstract

This study found that, in assessing the operability of esophageal cancer, the diagnostic sensitivity of metastasis detection in a high-volume referral center was higher than that in referring regional centers. This resulted from both better CT-scanning equipment and more experienced radiologists in the referral center. Should the decision to perform esophagectomy have only been based on metastasis detection in these regional centers, over 1 in 20 patients would have undergone resection in the presence of metastases.
